Dihydrogen monoxide hoax

"Dihydrogen monoxide" and "DHMO" redirect here. For the H2O molecule, see Properties of water. For Dental Health Maintenance Organization, see Dental insurance § Dental Health Maintenance Organization (DHMO).
The subject of the hoax, water, has a molecule consisting of two hydrogen atoms and one oxygen atom, thus the name dihydrogen monoxide.

The dihydrogen monoxide hoax involves calling water by the unfamiliar chemical name "dihydrogen monoxide" (DHMO), and listing some of water's effects in an alarming manner, such as the fact that it accelerates corrosion and can cause severe burns. The hoax often calls for dihydrogen monoxide to be regulated, labeled as hazardous, or banned. It illustrates how the lack of scientific literacy and an exaggerated analysis can lead to misplaced fears.[1]

The hoax gained renewed popularity in the late 1990s when a 14-year-old student collected anti-DHMO petitions for a science project about gullibility.[2] The story has since been used in science education to encourage critical thinking and avoid the appeal to nature.

History

A 1983 April Fools' Day edition of the Durand Express, a weekly newspaper in Durand, Michigan, reported that "dihydrogen oxide" had been found in the city's water pipes, and warned that it was fatal if inhaled, and could produce blistering vapors.[3] The first appearance of the hoax on the internet was attributed by the Pittsburgh Post-Gazette to the so-called "Coalition to Ban Dihydrogen Monoxide",[4][5] a parody organization started by UC Santa Cruz student Craig Jackson following the on-campus postings and initial newsgroup discussions.

This new version of the hoax was created by Eric Lechner, Lars Norpchen, and Matthew Kaufman—housemates while attending the University of California, Santa Cruz in 1989,[6] revised by Jackson in 1994,[4] and brought to widespread public attention in 1997 when Nathan Zohner, a 14-year-old student, gathered petitions to ban "DHMO" as the basis of his science project, titled "How Gullible Are We?"[2]

Jackson's original site included the following warning:[7][8]

Dihydrogen monoxide:

  • is also known as hydroxyl acid, and is the major component of acid rain.
  • contributes to the "greenhouse effect".
  • may cause severe burns.
  • contributes to the erosion of our natural landscape.
  • accelerates corrosion and rusting of many metals.
  • may cause electrical failures and decreased effectiveness of automobile brakes.
  • has been found in excised tumors of terminal cancer patients.

Despite the danger, dihydrogen monoxide is often used:

  • as an industrial solvent and coolant.
  • in nuclear power plants.
  • in the production of styrofoam.
  • as a fire retardant.
  • in many forms of cruel animal research.
  • in the distribution of pesticides. Even after washing, produce remains contaminated by this chemical.
  • as an additive in certain "junk-foods" and other food products.

A mock material safety data sheet—a list of information about potentially dangerous materials used in research and industry—has also been created for H2O.[9][10]

Molecular terminology and naming conventions

The water molecule has the chemical formula H2O, meaning each molecule of water is composed of two hydrogen atoms and one oxygen atom. Literally, the term "dihydrogen monoxide" means "two hydrogen, one oxygen", consistent with its molecular formula: the prefix di- in dihydrogen means "two", the prefix mon- in monoxide means "one", and an oxide is a compound that contains one or more oxygen atoms.[11]

Using chemical nomenclature, various names for water are in common use within the scientific community. Some such names include hydrogen oxide, as well as an alkali name of hydrogen hydroxide, and several acid names such as hydric acid, hydroxic acid, hydroxyl acid, and hydroxilic acid. The term "hydroxyl acid" used in the original text is a non-standard name.[12]

Under the 2005 revisions of IUPAC nomenclature of inorganic chemistry, there is no single correct name for every compound.[13] The primary function of chemical nomenclature is to ensure that each name refers, unambiguously, to a single substance. It is considered less important to ensure that each substance should have a single name, although the number of acceptable names is limited.[13] Water is one acceptable name for this compound, even though it is neither a systematic nor an international name and is specific to just one phase of the compound. The other IUPAC recommendation is oxidane.[14]

Public efforts involving the DHMO hoax

DHMO in education and debate

The DHMO hoax has been used in science education to encourage critical thinking and discussion of the scientific method.[33][34]

Jennifer Abel from Consumer Affairs also said: "search online for information about dihydrogen monoxide, and you'll find a long list of scary and absolutely true warnings about it: used by the nuclear power industry, vital to the production of everything from pesticides to Styrofoam, present in tumors removed from cancer patients, and guaranteed fatal to humans in large quantities."[35]
